Decomposing Shapes and Their Properties

The video tutorial teaches students how to decompose larger two-dimensional shapes into smaller ones. It begins with an introduction to the concept of decomposing shapes, followed by identifying various shapes like rectangles, trapezoids, circles, triangles, pentagons, and rhombuses. The tutorial then demonstrates how to decompose a hexagon using smaller shapes such as trapezoids, rhombuses, and triangles. Another example is provided, showing the decomposition of a different shape using trapezoids and triangles. Finally, students are given instructions for a hands-on activity to practice decomposing shapes using cut-out pieces and recording their findings on Pear Deck slides.

What is the main idea behind decomposing shapes?

• Combining smaller shapes into a larger one

• Breaking a larger shape into smaller shapes

• Changing the color of a shape

• Rotating shapes to fit a pattern

Which of the following is NOT a shape mentioned in the lesson?

• Circle

• Octagon

• Hexagon

• Rectangle

What is the objective of the lesson on decomposing shapes?

• To memorize the names of shapes

• To create new shapes from scratch

• To draw shapes freehand

• To break a larger shape into smaller shapes and record the results

What is the first step in decomposing a shape according to the lesson?

• Erase the existing shape

• Draw a new shape

• Choose a color

• Identify the larger shape

In the first example, which shape is used first to decompose the hexagon?

• Circle

• Trapezoid

• Triangle

• Rhombus

Why was the square not used in the first example of decomposing the hexagon?

• It was not available

• It was the wrong color

• It did not have a right angle

• It was too large

Which shape was used to fill the remaining part of the hexagon in the first example?

• Pentagon

• Rectangle

• Circle

• Upside-down triangle
